While Goldberg and Gilroy have alluded to mixed-race metaphors in their recent work, Lewis Gordon has written more extensively about the attempts to establish 'critical' mixed-race studies. Reflecting on the historical discrimination and colourism in an anti-black world, Gordon has argued that it is understandable – if not morally justifiable – for working-class individuals and darker-skinned individuals to be distrustful of middle-class individuals and lighter-skinned individuals who claim to be progressive. Gordon's use of slime to describe the aims of a wide variety of mixed-race activists and 'sensitive' scholars – who talk politely about racial transcendence while denying the facticity of their privileged position in an anti-black world – is a particularly interesting term since it evokes animalistic behaviour, infantile play, salesmen pitching new, hip commodities for a polyethnic culture. It also offers a transracial, transdisciplinary and transnational engagement with Francophone theory. Aside from adapting Fanon's critique of European man, Gordon's analysis of multiracial celebration draws on Sartre'sontology of slime (a sticky, viscoelastic material that resists shear flow and strain linearly with time when a stress is applied,) and reminds us of Barthes's famous description of neither-norism (a 'mythological figure which consists in stating two opposites and balancing the one by the other so as to reject them both... It is on the whole a bourgeois figure, for it relates to a modern form of liberalism... one flees from intolerable reality … one no longer needs to choose, but only to endorse.')

Throughout her book, Osuji uses her findings to challenge the notion that society should rely on interracial couples and their multiracial children to end racism.

While people in American society often talk about race mixture as an antidote to the countryâ€™s racial problems, interracial couples remain stigmatized, according to a new book by a Rutgers Universityâ€“Camden sociologist.

â€śThe idea is that, the more people who are interracially marrying, then we will have more multiracial children and magically there wonâ€™t be racial inequality or racism anymore,â€ť says Chinyere Osuji, an assistant professor of sociology at Rutgers Universityâ€“Camden.

Thatâ€™s not the case, says the Rutgersâ€“Camden researcher.

According to Osuji, looking at interracial couples in Brazil â€“ a country historically known for its racial diversity â€“ shows how racism can coexist with race mixture. She explains that, although the country does have a substantial multiracial population, interracial couples are very much still stigmatized and race mixing is segregated by class â€“ more likely to occur â€śin poor communities, where brown and black people live.â€ť
